## How to Assign Alphabets to Numbers for Printing Encrypted Rates in Barcodes?

In this tutorial, we’ll learn how to **assign alphabets to numbers** and use this mapping for **rate encryption in barcode labels** in **Logic ERP**.

***

### **Open the Assign Alphabets to Numbers Module**

* Navigate to the **Assign Alphabets to Numbers** module.
* You will see **digits from 0 to 9** listed in the **Number** column.

**Map Alphabets to Numbers**

* In the **Alphabet** column, assign a **unique alphabet** to each number (0–9).
* This alphabet-to-number mapping will be used for **barcode rate encryption**.
* Ensure every digit from **0 to 9** has a corresponding alphabet.
